CVE-2025-41363 is a medium severity vulnerability identified in ZIV's IDF and ZLF products, specifically versions v0.10.0-0C03-03 and v0.10.0-0C03-04. The vulnerability stems from a permissive cross-domain policy configuration error related to Cross-Origin Resource Sharing (CORS), categorized under CWE-942 (Permissive Cross-domain Policy with Untrusted Domains). This misconfiguration allows authenticated users with only view permissions to execute certain commands that should be restricted, potentially enabling unauthorized actions or data access across domains. The vulnerability requires authentication but does not require user interaction beyond that, and it can be exploited remotely (network vector) with low attack complexity. The CVSS 4.0 base score is 5.3, reflecting a medium severity level, with the vector indicating no user interaction, no additional privileges beyond low-level authentication, and no impact on confidentiality, integrity, or availability directly, but with scope changed, implying some escalation or broader impact within the system. The lack of known exploits in the wild suggests it is not yet actively exploited, but the configuration error could be leveraged by attackers who gain authenticated access to the device. The vulnerability affects cross-origin resource sharing policies, which are critical for web applications and devices that interact with multiple domains, potentially allowing malicious domains to bypass intended security restrictions if the policy is too permissive. Since the affected products are specialized ZIV devices (likely industrial or infrastructure-related), the impact could extend to operational environments relying on these devices for control or monitoring functions.

For European organizations, especially those in critical infrastructure sectors such as energy, manufacturing, or utilities where ZIV products like IDF and ZLF might be deployed, this vulnerability poses a risk of unauthorized command execution within authenticated sessions. Although exploitation requires authentication with view permissions, the permissive CORS policy could allow attackers to perform cross-domain attacks that bypass normal security boundaries, potentially leading to unauthorized data exposure or manipulation of device behavior. This could disrupt operational technology (OT) environments or lead to information leakage. The medium severity rating reflects that while direct impact on confidentiality, integrity, or availability is limited, the vulnerability could serve as a stepping stone for more advanced attacks or lateral movement within networks. European organizations with these devices in their infrastructure should be aware of the risk of internal or insider threats exploiting this vulnerability, as well as attackers who have gained low-level credentials. The absence of known exploits reduces immediate risk but does not eliminate the potential for future exploitation.

To mitigate this vulnerability, European organizations should: 1) Immediately review and tighten the CORS policies on affected ZIV IDF and ZLF devices to restrict cross-origin requests only to trusted domains, eliminating permissive or wildcard entries. 2) Enforce strict access controls and monitor authentication logs to detect any unauthorized or suspicious access attempts, especially from users with view permissions. 3) Implement network segmentation to isolate these devices from less trusted network zones and limit exposure to authenticated users only. 4) Regularly audit device configurations and update to the latest firmware or software versions once patches become available from ZIV. 5) Employ multi-factor authentication (MFA) for device access to reduce the risk of credential compromise. 6) Conduct internal security awareness and training to reduce the risk of credential misuse by insiders. 7) Monitor for unusual cross-domain traffic patterns that could indicate exploitation attempts. Since no patch links are currently available, organizations should engage with ZIV support for timelines and interim mitigations.
